Whether you live in a minimalist apartment and get around on public transit, or own a big house with a two-car garage, you and your spouse probably own a significant amount of property, and if you're like most people, you have debts as well. If you're going through a divorce, you have to make decisions about how to divide the property and the debts. Ideally, you and your spouse will decide together how you want to divide the marital property--you'll have to decide things like whether one of you will keep the family home and buy out the other spouse's interest or whether you'll sell the house; who will keep the furniture and other tangible property; how you'll divide retirement assets that each of you has accrued through your work; and how to deal with marital debts. If you can't make decisions yourselves, you'll have to ask the court to resolve your property questions.
